400~520nm (blue) – This wavelength can directly develop plant roots and stems, and has the largest absorption ratio of chlorophyll and carotenoids and the greatest impact on photosynthesis. Spydrx Plus Led Grow Light, Led Grow Light Lm301H , Light Led Grow , Grow Light Led ,3360 Led Grow Light . In terms of illumination, LED lighting can guide the space, create a pleasing lighting environment, convey the value information of the space, and render the space with light. In terms of color temperature, the cooling and warm feeling of the lighting effect formed by the light source of different color temperature of the LED complements the difference in climatic conditions, and the designer makes the indoor space full and enjoyable through the grasp of the color temperature of the light. In terms of light efficiency, LED lighting can reduce energy consumption (high light efficiency). In addition, LED lighting also does not produce infrared radiation and ultraviolet rays, low temperature, long life, energy saving and other advantages, since this is the case, then why LED lighting is not the darling of indoor lighting? What are its disadvantages? The product will supply to all over the world, such as Europe, America, Australia,Jamaica, Iran,Kyrgyzstan, Bhutan.LED plant lights help shorten the growth cycle of plants, because the light source of this lamp is mainly composed of red and blue light sources, using the most sensitive light band of plants, red light wavelengths use 620-630nm and 640-660nm, blue light wavelengths use 450-460nm and 460-470nm.
